HOLDER FOR GRAPHIC INSTRUMENTS.

Application iii-ed February 16, 1925. Serial n... 9,450.

ments, of which the following is a complete specification.

This invention relates to a holder for graphic instruments such as apen, pencil,

' brush or stylus where it is desired to secure a uniform weight on theoperating point and a consequently uniform line regardless of whetheradown, up or lateral stroke 1 is being made.

Another object is toproduce a holder of the general character outlinedhaving means whereby the holder can be adjusted to accommodate the angleat which various writers may habitually hold the graphic instrument.

A further object is to provide a holder of the general charactermentioned which may be readily provided with additional weight to pressharder on the working point.

A still further object is to produce a graphic instrument holder of thecharacter outlined which is of strong, simple, durable and inexpenisveconstruction; and in order that it may be fully understood, reference isto be had to the accompanying drawing, in which a v Figure 1 is acentral vertical section taken through aholder embodying the invention,it being noted that it is illustrated in connection with a writin pen,the body of the pen being somewhat s orter than would be the case inactual practice. Figure 2 is a section similar to that of Figure 1 butat ri ht angles thereto.

Figure 3 is a si e elevation of the pen as it will appear when not inuse.

Figure 4 is a section on the line IVIV of Figure 1.

In the said drawing, where like reference characters identifycorresponding parts in all of the figures, 1 indicates the barrel of afountain pen equipped with the customary nib 2 and internal ink sack 2,said barrel being of any common or ordinary type and of c lindricalform. Molded integrally with the arrel, on opposite sides thereof andextending laterally therefrom, are a pair of ribs 3.

. The pen 1 is received within a holder 4 having a bore of sufiicientdiameter to slidinafter appear.

ingl receive the en, and adjacent the point of t e pen, said older hasan enlarged internal recess 6 for a purpose which will here-Communicating with said recess are the ends of a pair of oppositelydisposed internal slots 7 for the reception of the ribs 3 of the barrelof the pen, it being understood that the slots are of greater lengththan the ribs.

The internal face of the recess 6 is threaded for the reception of athreaded sleeve 8 having its bore of sufficient diameter to snuglyreceive the barrel of the pen without offering any appreciableresistance to the sliding thereof. The barrel of the pen is thus freefor sliding back and forth within the holder, being limited in itsrearward movement through contact of the rear ends of the ribs 3 withthe rear ends of the slots 7, and in its forward movement throughcontact of the front ends of the ribs 3 with the collar 8, theinterlocking ribs and slots also serving to prevent rotation of the penbarrel. By threading the sleeve 8 back and forth, the range of forwardmovement of the pen may be adjusted to fit varying conditions as willhereinafter appear.

Secured to the holder 4at a point in line with the pen nib is a fixedguide 9 bowed out to permit the pen cap 10 to be screwed on the end ofthe holder as common, and

said guide is equipped with a ball extremity at its lower end. When thedevice is in use the guide 9 will be in constant contact with the writinsurface and transmits all of the pressure 0 the writers hand direct tosuch surface. The pressure on the writing point is thusthat of theweight of the pen barrel alone and a uniform line is thus secured,although, if desired, suitable weights may be inserted in the end of theholder as at 11 to press down on the pen barreland increase tihepressure on the point to trace a heavier In the use of the device, theguide 9 is always maintained in contact with the writing surface, thepen point being elevated at the end. of a word and the like, by a slightmovement in the direction indicated by the arrow a around the end of theguide. This I movement effects the upward sliding movement of the holderuntil the sleeve 8 abuts the ends of the ribs 3 and consequently degreeof movement of the holder necessary to elevate the point may be adjustedby manipulation of the sleeve 8, this adjustment also being necessary tocompensate for the different angles at which various users may hold thepen.

In actual use, the pen barrel will possess but a slight range of slidingmovement, as the angle of the pen in writing is seldom shifted to anygreat extent. The proportion of the parts will be such that the end ofthe barrel of the pen will be just about parallel with the end of theholder when the pen is at its limit of inward or inoperative position.

As it may be desirable at times for the operator to press with a greaterforce of the nib of the pen than-that ofthe weight of the barrel sleeve,a friction plug 12 (see Figure 1), is mounted in the holder 4 andslightly projects therefrom. The inner end of said plug terminates in anenlarged face 13 for engagement with the barrell of the pen. With thisconstruction it will be apparent that the operator can arrest thesliding movement of the pen when he desires to cross\a letter T or thelike, by imposing pressure on the projecting end of the plug.

From the above description it will be apparent that I have produced aholder of the character outlined which possesseslall 0f the features ofadvantage set forth as desirable,

and while I have described and claimed the the right to make all changesproperly falla ing within the spirit and scope of the appended claims.

I claim:

1. A holder, a guide on said holder, a graphic instrument freely slidingin said holder, means for preventing the rotation and limiting thesliding movement of said instrument in one direction, and adjustablemeans for limiting the sliding movement of the instrument in the otherdirection.

2. A holder havin an internal slot, a

graphic instrument reely sliding in said holder and having a ribengaging the slotof the holder, an external guide secured to saidholder, and an adjustable sleeve adapted to be adjusted to limit thesliding movement of the instrument in one direction within predeterminedlimits. 3. A holder having an internal slot, and an internal recess atone end, a graphic instrument freely sliding in said holder and having arib engaging the slot of the holder, and an adjustable sleeve in saidholder recess adapted to limit the sliding movement of said instrumentin one direction.

4. A holder, a guide on said holder, a graphic instrument freely slidingin said holder, means for preventing the rotation and limiting thesliding movement of said instrument in one direction, adjustable meansfor limiting the sliding movement of the instrument in the otherdirection, and friction means for preventing the sliding movement ofsaid instrument.

5. A holder having an internal longitudinal slot and at one end anenlarged threaded recess, a graphic instrument freely sliding in saidholder and having a rib engaged with the slot thereof, a sleeve threadedin the end recess of said holder, and a manually'operable frictiondevice carried bv the holder and adapted to 1 apply friction againstsaid graphic instrument.

In witness whereof I hereunto afiix my signature.
